EA-PS 10080-120 2U 3000W Programmable DC Power Supply

The EA-PS 10080-120 2U is a high-performance programmable DC power supply designed for demanding laboratory, test bench, and industrial applications. With an output range of 0–80 V and 0–120 A, it delivers up to 3000 W of clean, stable DC power. The unit features a compact 2U 19-inch rack-mountable design, a 5-inch color TFT touchscreen interface, and supports multiple control modes including constant voltage (CV), constant current (CC), constant power (CP), and internal resistance simulation (CR). It includes built-in USB and Ethernet interfaces, an isolated analog programming port, and optional digital interface modules (CAN, CANopen, Profibus, ProfiNet, ModBus TCP, EtherCAT, RS232). The device supports parallel master-slave operation for up to 64 units, delivering scalable power up to 192 kW. With high efficiency (≤94%), low ripple, and comprehensive protection features (OVP, OCP, OPP, OT, PF), it is ideal for testing batteries, powering sensitive loads, and serving as a programmable DC source or sink.
